Modulation can be helpful if you use it for lasers in projectors or scanners for lasershows, for the blanking signal and for the "color mixing" signals ..... or, at the limit, just for build a labby unit that you can regulate from different levels ..... not indispensable, just an extra

Nono. I know full well that it was optional. Just curious why/when it is needed outside of telecommunications applications was all.

Oh, this ..... more than all the other, for blanking / color mixing in lasershows, probably ..... or, at least, 99% of the times i've seen modulation used in laser drivers, that was for this reason .....
